Library Indicator (high visibility)
I sometimes forget which Library I have loaded. The indicators in my OS Window title, and the calibre Library icon/text, do not stand out enough for my old eyes. It would be great to see something to the menubar with high visibility to indentify the current library.
Maybe a drop down library selector that has an icon which changes based on the library (with user provided icons)?
Or, maybe a text field/area on the menu bar, with some font/background options to display the library name or a short nickname?
Also, IMHO: The current Library icon would be better if the drop down showed all libraries (not just the unloaded ones) with a check next to the 'loaded' one.
